Even if you look at the blade wrong, it'll cut you. Amazing sharpness, mirrored finish, beautiful design. Check out other sites first-- minimium I've seen is $3900.This Rockstead UN-ZDP fixed blade knife is handcrafted in Japan and built around ZDP-189 super steel, one of the hardest stainless steels ever used in a production knife. New in the box.

With a measured hardness around HRc 67, this blade delivers extreme edge retention and durability that few knives can match. The Honzukuri blade geometry, combined with a full mirror polish, results in exceptional cutting performance and reduced drag through dense materials.

The UN-ZDP is well known among collectors and reviewers for real-world performance tests, including cutting through stacked phone books, carving and splitting wood while retaining a razor edge, and even surviving extreme stress tests such as being shot without catastrophic failure. These demonstrations highlight Rockstead’s heat treatment and grinding precision.
